Arduino Partners with Chirp to Enable Data-Over-Sound M2M Connectivity

Announced on August 12, 2019, Arduino has partnered with the London-based Chirp, a wireless data-over-sound software solution for machine-to-machine connectivity. The system has the ability to work online or offline, as long as there is a loudspeaker and a microphone available. The software works with the Arduino Nano 33 BLE Sense board in send and receive mode, while most Arduino MKR boards and Arduino Nano 33 IoT will also be supported by the SDK, but only to send data. The software and board are fully compatible with SDKs from a wide variety of platforms. The Nano 33 BLE Sense is available for purchase from the Arduino website, for $29.50. The sensor-rich Arduino Nano 33 BLE Sense is application-ready right out of the box, and Chirp is ready to start sending encoded data from a device fitted with an audio speaker, to the board’s built-in microphone, where it is encoded and […]

Linaro Connect San Diego 2019 Schedule – IoT, AI, Optimizations, Compilers and More

Linaro has recently released the full schedule of Linaro Connect San Diego 2019 that will take place on September 23-27. Even if you can’t attend, it’s always interested to check out the schedule to find out what interesting work is done on Arm Linux, Zephyr OS, and so on. So I’ve created my own virtual schedule with some of the most relevant and interesting sessions of the five-day event. Monday, September 23 14:00 – 14:25 – SAN19-101 Thermal Governors: How to pick the right one by Keerthy Jagadeesh, Software Engineer, Texas Instruments With higher Gigahertz and multiple cores packed in a SoC the need for thermal management for Arm based SoCs gets more and more critical. Thermal governors that define the policy for thermal management play a pivotal role in ensuring thermal safety of the device. Choosing the right one ensures the device performs optimally with in the thermal budget. […]

Somu Tiny Open Source FIDO2 Security Key Enables Passwordless Login & Two-factor Authentication (Crowdfunding)

Tomu is a tiny, open source USB connector-sized board powered by a Silicon Labs Happy Gecko Cortex-M0+ MCU that adds two keys to your computer and can work as a Universal 2nd Factor (U2F) token to support two-factor authentication (2FA). But the board is not secure enough for FIDO2 support, and Tomu’s developer worked on a secure USB key called Solokey, and shrank it to Tomu form factor. Meet Somu open-source and secure key with FIDO2 support for compatibility with your Google, Twitter, and GitHub accounts for two-factor authentication, or your Microsoft account passwordless login. Somu hardware specifications: Secure MCU – STMicro STM32L432KC Arm Cortex-M4 microcontroller with TRNG, security isolation for keys, two levels of locked flash Crypto Algorithms – ECC P256 (as per FIDO2 standard) Supported Protocols – FIDO2, U2F Host Interface – USB type-A port Misc – Two touch buttons ( in FIDO2 firmware the two buttons behave […]

Rock Pi 4 SBC Runs GNOME & KDE Plasma using Panfrost Open Source GPU Driver & Wayland

One of the highlights of Linux 5.2 release was support for two new Arm Mali GPU open-source drivers, namely Lima for Mali-4xx GPU, and Panfrost for the Midgard Mali-T6xx/7xx/8xx series, and the more recent Bifrost Mali-Gxx GPUs. Collabora worked on the release and was donated a few Rock Pi 4 boards from Radxa directly to work on the project. For those who are not familiar, Rock Pi 4 board is powered by a Rockchip RK3399 processor with a Mali-T860MP4 GPU that is supported by Panfrost open source GPU driver. The company managed to have Debian 10 Buster running on Rock Pi 4 using 3D graphics acceleration thanks to Panfrost drivers on both GNOME and KDE Plasma desktop environment, as well as Weston Wayland compositer. The good news is that you can build Rock Pi 4 images by yourself using Debos with the following commands:

git clone https://gitlab.collabora.com/rockpi/rockpi4
cd rockpi4
docker run --rm --interactive --tty --device /dev/kvm --workdir /recipes --mount "type=bind,source=$(pwd),destination=/recipes" --security-opt label=disable godebos/debos --scratchsize=8G rockpi4.yml

git clone https://gitlab.collabora.com/rockpi/rockpi4

cd rockpi4

docker run --rm --interactive --tty --device /dev/kvm --workdir /recipes --mount "type=bind,source=$(pwd),destination=/recipes" --security-opt label=disable godebos/debos --scratchsize=8G rockpi4.yml

Alternatively, you could directly download […]
